Watering - Requires regular watering during dry periods and keep area free of weeks.
Fertilising - Well rotted animal manure, blood and bone, or a complete fertiliser should be worked through the soil prior to planting. Top dress with some fertiliser or liquid feed every 4-5 weeks through the growing season.
Lifting and storage - Can be lifted during the winter months or left in the ground for many years. If lifted, store temporarily in moist peat moss.
Pests - Place some snail bait around the plants as snails and slugs love the young shoots. Watch for thrip and aphids and spray occasionally if required.
Tips - Plant crown at soil level. Delphiniums are easily grown, frost tolerant and like sunny positions in a rich well drained soil. Plant near fence lines or towards the back of a garden bed as they are tall growing. Ideal cut flowers. Delphiniums prefer a neutral soil. Add lime to raise the ph of acidic soils prior to planting.
